Fabrication of g-C3N4 Microspheres without Template via Microwave Heating Method

摘要：

　　This research reported the preparation of the graphitic carbon nitride (g-C3N4) microspheres without template via microwave heating method using melamine as precursor.The as-synthesized samples were characterized by powder X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), field-emission scanning electron microscopy (FE-SEM), ultraviolet-visible (UV-Vis) and photoluminescence (PL).Results showed that the g-C3N4 microspheres were successfully synthesized.The diameters of the microspheres range from 800 nm to 1.5 μm, and the shell thickness is about 50 nm.UV-Vis absorption edge and PL peak of the g-C3N4 were shown at 457 nm and 468 nm, respectively, indicating the intrinsic semiconductor-like absorption in the blue region of the visible spectrum.This was the first attempt to prepare g-C3N4 microspheres without template via microwave heating approach, which was proved to be facile and effective.
